I have had a really bad bug were all my arma player profiles are not there, I go to change a name and bam! they are all gone and now I have a invisible name, I have reinstalled arma over 3 times now! restarted my PC, verified game cache over 7 times and much more the only way I can even play is to run a parameter in the arma that will select a profile but I am completely stuck on what to do when I need to change it in the near future below is an attached video to try show the bug, I already searched online and found 1 single forum that was not even helpful and there are no youtube videos on this bug either.
